sco_datacore_v1.add_instance

Catalogue snapshot — development preview

SDK 2.3.0 · game pack 0.6.0 · source e616ed69d8f9f77b0f4827881c86d91e4a7d1689 Published release: sdk-v2.3.0 (immutable approved assets; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

A new instance of struct type, copied from clone_record’s clone_field (NULL or “”: the record’s root) or zero-filled (clone_record NULL). out_instance: its id, usable in this patch’s SCO_DC_INSTANCE values and set_pointer. Implementation initializes out_instance to 0 on failure.

Limitations / unestablished guarantees

• Internal allocation/failure guarantee unspecified.
• Recursive/concurrent same-patch reentrancy unspecified.
• Additional failures/output state unspecified unless described in the buffer contract.

Header source

Parameters and buffers

sco_result (*add_instance)(uint64_t patch, const char* type, const char* clone_record, const char* clone_field, uint64_t* out_instance);
A new instance of struct type, copied from clone_record’s clone_field (NULL or “”: the record’s root) or zero-filled (clone_record NULL). out_instance: its id, usable in this patch’s SCO_DC_INSTANCE values and set_pointer. Implementation initializes out_instance to 0 on failure.

Results and failures

Absent table: query_service NOT_FOUND; stopped operations: UNAVAILABLE. Unknown/released patch: NOT_FOUND; closed patch: BAD_ARG; operation cap: TOO_MANY. Additional failures/output state unspecified unless described in the buffer contract.

Absent capability

Absent table: query_service NOT_FOUND

Ownership

Strings/values copied; host owns patches and instances; IDs, not allocations, cross the ABI. Internal allocation/failure guarantee unspecified.

Thread affinity

Any thread; short locks, no wait for game load. Recursive/concurrent same-patch reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation; discard drops open/queued patch, not applied or saved effects. Unload forgets owned patches.

Language mappings

Status labels are copied verbatim from the catalogue: direct is native access; typed-wrapper is wrapper-backed; restricted is a subset/adaptation; unsupported means no supported route is established. No status implies universal safety.

Language	Catalogue status	Source evidence / wrapper tokens
